Patent US10602679
Issued 2020-03-31
Harvesting Tumbler
A harvesting tumbler apparatus includes first and second spaced apart grating segment retainers, and a tumbler grating including a plurality of resiliently tensionable grating segments connected to the first and second grating segment retainers. The resiliently tensionable grating segments extend from each of the first and second grating segment retainers in a spaced apart circular arrangement. The tumbler apparatus further includes a tension mechanism configured to apply a sufficient tension force to the resiliently tensionable grating segments to cause the grating to form a cylindrical shape. In illustrative embodiments, the resiliently tensionable grating segments may include flexible cord segments.

- 1. A harvesting tumbler apparatus comprising:
first and second spaced apart grating segment retainers; a tumbler grating comprising a plurality of resiliently tensionable grating segments connected to the first and second grating segment retainers, the resiliently tensionable grating segments extending from each of the first and second grating segment retainers in a spaced apart circular arrangement; and a tension mechanism configured to apply a sufficient tension force to the resiliently tensionable grating segments to cause the grating to form a cylindrical shape.
- 17. A tumbling method comprising:
rotating a tumbler grating comprising a plurality of resiliently tensionable grating segments that extend in a circular arrangement between first and second grating segment retainers, while applying a sufficient tension force to the tumbler grating to cause the tumbler grating to maintain a cylindrical shape; and propagating plant material axially through an internal volume of the tumbler grating while maintaining the rotating tumbler grating in proximity to a cutting knife to cut plant material protruding radially outward from the tumbler grating.
